VALID 161200Z - 211200Z

....DISCUSSION...
MEDIUM-RANGE MODELS CONTINUE TO DEPICT A SUBSTANTIAL EXPANSION OF
THE LARGE-SCALE RIDGE -- WHICH WILL PREVAIL ACROSS A LARGE PORTION
OF THE U.S. THROUGH THE PERIOD.

GIVEN THE EXPANSIVE RIDGE...MAIN SEVERE POTENTIAL WILL EXIST ALONG
THE NRN PERIPHERY OF THE FEATURE -- I.E. FROM THE NRN ROCKIES/NRN
INTERMOUNTAIN REGION ARCING EWD ACROSS THE INTERNATIONAL
BORDER/GREAT LAKES REGION...AND THEN ESEWD INTO NEW ENGLAND AND
VICINITY. HOWEVER...WITH THE DEGREE/LOCATION/TIMING OF THREAT AREAS
MODULATED STRONGLY BY SMALL-SCALE/FAST-MOVING DISTURBANCES EMBEDDED
WITHIN THE ANTICYCLONIC FLOW FIELD AROUND THE NRN FRINGE OF THE
RIDGE...PREDICTABILITY REMAINS LOW AND THUS WILL NOT INTRODUCE ANY
THREAT AREAS THIS FORECAST.
